Community

Over the past year, GitHub partnered with, held, and sponsored events all over the world. At Patchworks we watched new developers learn how to use Git. Our ConnectHome partnership provided low-cost internet access for families living in HUD-assisted housing. Sponsoring events like Rails Girls and hosting our own conferences allowed us to meet more GitHub users than ever before.

Newcomers

This year GitHub grew by more than 5.2 million users and 303K organizations. We have more new students, developers, and businesses using GitHub than ever before.

Like this Comic Book Search Engine repo created by @katana171. She was one of our Patchwork Toronto attendees, and even though she was new to GitHub, she jumped in with both feet, and wasted no time building a useful and fun project that anyone can contribute to.

It’s not just technology companies either—from retailers to healthcare and financial services companies—GitHub Enterprise provides the security and easy management these types of businesses require with the same GitHub experience developers love.
